I don't disagree with your assessment, and I'll try and see what can be done about the firmware (your comments should help on that front). This was just the most expedient thing for me to do (I'm not a firmware developer) to get yaboot to work with the new firmware.<br>
<br>
<br>
Thanks,<br>

According to PAPR 2.0<br>
<br>
C.11 Support Packages<br>
This section describes the PAPR Binding specific requirements of OF<br>
support packages. These support packages are disk-label and tape-label.<br>
For “network” and/or obp-tftp extensions, refer to Open Firmware:<br>
Recommended Practice - TFTP Booting Extensions, Version 0.8 [10]. These<br>
packages support the loading and executing of a client program. Another<br>
means of executing a Client Program is provided when an OS ROM is a<br>
“bootable device”<br>
<br>
<br>
C.11.3 network Support Package<br>
The network Support Package shall adhere to the Open Firmware:<br>
Recommended Practice - TFTP Booting Extensions, Version 0.8 [10]<br>
documentation functions and conventions.<br>
<br>
Sounds as if this is untrue - I can't find version 0.8 but both 0.6d and<br>
1.0 use the optional language.<br>
<br>
Sounds as if JS21 GA3 firmware fails to pass PAPR binding requirements.<br>
